In this video, Mr. Hamilton shows how to solve some more difficult trigonometric identities for grade 11 math.
If you have not yet seen the first video about proving trigonometric identities can be found here: • Proving Trig Identitie...

sin@cos@tan@=1-cos^2@ to be proved
p=pependicular
b=base
h=hypotenuse, therefore the above will be
p/h×b/h×p/b=1-b^2/h^2
p^2/h^2=1-b^2/h^2
now, 1-b^2/h^2=(h^2-b^2)/h^2
by phytogores therom h^2-b^2=p^2
hence left hand side=right hand side
